5.3
Changing Fastener Types
Because of the variety of materials being used to make molding, no single fastener can meet
every need. That’s why all MitreNailer
machines can drive several different types of
fasteners.
“V” Fasteners – For soft woods plastics, and
very delicate moldings. Driven with a
“press” type tool. Available in 7, 10, 12, &
15 mm heights, All heights available in
hardwood or regular.
7/16”
L-Nails – “V” shaped fastener made from
stronger material for soft or hard woods and
thin moldings. Driven with a “velocity” tool.
Powerful enough to drive into the hardest of
woods. Available in 5/16”, 7/16”, & 9/16”
heights. Specify hardwood or regular.
7/16”
Micro Corrugated – For strong, tight corners
in harder woods and MDF. Angled “flutes”
actually draw miscut molding together and
create a corner with exceptional strength.
Available in 1/4”, 3/8”, 1/2”, & 5/8” heights.
Specify hardwood or regular
1/2”
Mini-Corrugated – For Mirrors and
other heavy, large frames and extra
wide molding where joint strength is of
paramount importance. Available in
1/4”, 3/8”, & 1/2” heights.
11/16”

Maintenance
DAILY:
Check Lubricant Level
Lubricant level can be viewed through the bowl. To add oil: Disconnect air, Loosen bowl 1/4 turn & pull downward to
remove, fill oil to just below top of window. Oil can be added through the fill port while the machine is still pressurized.
Important!! Use only 10 wt. non detergent oil. Use of any other lubricant will damage rubber seals and cause machine to
malfunction.
Drain Air Filter
Open valve at bottom of filter until all water drains, close valve when water is completely drained. This can be done with
the machine pressurized.
Check Air Leaks
Check for air leaks on hoses, cylinders, and valves and replace accordingly.
Visual Inspection
Check for loose or missing screws, bolts, and pins and tighten or replace as required.
Clean Machine
Wipe down or blow off entire machine paying particular attention to the valve assembly, the driving tool, and all moving
components.
WEEKLY:
Lubrication
With an oil dampened rag, lightly coat the bearing rods on the holddown and carriage as well as all cylinder rods.
NOTE: Use a 10 wt. Non detergent oil. Use of other oils or lubricants can damage the machine.
Electrical Connections
Visually inspect any electrical wires for fraying or excessive wear. Replace as required.
MONTHLY:
Filter Element
Inspect the filter element and wipe out the bowl with a clean cloth. Replace the filter element if dirty or causing a drop
in pressure of 10 lbs. or more.
Grease all “zirc” fittings on the Holddown and the tool carriage bearings. In extreme conditions, this may have to be
done more ofter.
IMPORTANT! Before greasing Holddown bearings, disconnect air from machine and push the holddown assembly to
the bottom of its stroke. Failure to do this will cause excessive buildup of grease and adversely affect operation of the
Holddown system.
Pneumatic Valves
Clean and lubricate pneumatic valves as indicated. See instructions on page 6.2 and 6.3.
Cleaning and Lubricating Pneumatic Valves – Double Shooter
NOTE: This procedure should be done every 2 to 3 months on a machine in heavy production or when the
machine begins to function sluggishly. A “dirty” air supply (excessive water or particulate matter in the air
lines) will increase the required cleaning frequency.
Disconnect Air Supply to Machine before
cleaning Valves.

Next, gently remove the Spring, the O-Ring, and the Rubber Bumper from the Valve. Wipe them clean and
coat with a light film of 10 wt. non-detergent oil. These parts can usually be re-used if handled with care.
Repair kits are available if these parts are damaged. Specify the valve number when ordering.
Rubber PA-4000 for
valves with springs (#1, #2, & #4); PP-4000
Bumper
for valve without spring (#3).
4. With a pair of needle nose pliers gently remove
Valve
the Valve Spool from the Valve. Wipe the
Cover and
Valve Spool with a clean cloth. If mineral
deposits have built up on the spool, they can be
removed with a fine grit polishing compound.
Coat the Valve Spool with light film of 10 wt.
non-detergent oil. Carefully re-insert the Spool
into the Valve and spin it to distribute the oil
inside the valve. Check to be sure the Spool
moves freely inside the Valve.
